DETAILED DESCRIPTION

[0029] The present application is further described in detail below by means of specific embodiments in conjunction with the accompanying drawings. Similar elements in different embodiments are numbered with associated similar elements. In the following embodiments, many detailed descriptions are provided to enable the present application to be better understood. However, those skilled in the art will readily appreciate that some of the features may be omitted in different circumstances, or may be replaced by other elements, materials, or methods. In some cases, some operations related to the present application are not shown or described in the specification. This is to avoid the core portion of the present application being overwhelmed by excessive descriptions. For those skilled in the art, it is not necessary to describe these related operations in detail. They can fully understand the related operations based on the description in the specification and the general technical knowledge in the art.

[0030] In addition, the features, operations, or characteristics described in the specification may be combined in any appropriate manner to form various embodiments. Furthermore, the steps or actions in the method description may be reordered or adjusted in a manner readily apparent to those skilled in the art. Therefore, the various sequences in the specification and drawings are provided solely for the purpose of clearly describing a particular embodiment and are not intended to be mandatory, unless otherwise specified.

[0031] The serial numbers assigned to components herein, such as "first," "second," etc., are used solely to distinguish the objects being described and do not convey any sequential or technical meaning. References to "connection" and "coupling" herein, unless otherwise specified, include both direct and indirect connections (couplings).

[0032] In order to address the problem that the silk thread needs to be frequently tightened to keep it tightened around the soft tissue, which results in complicated operations, the present application provides a soft tissue elastic tightening device that applies elastic force to the silk thread through an elastic member to continuously maintain the tightening effect on the soft tissue and reduce the frequency of tightening the thread.

[0033] In one embodiment, please refer to Figures 1 to 9 The soft tissue elastic tightening device includes a mounting base 1, a thread 2, and an elastic member 3. The thread 2 is used to tighten soft tissue and includes a movable segment 21 and an operating segment 22 disposed on the mounting base 1. The movable segment 21 is connected to the elastic member 3, enabling the elastic member 3 to exert an elastic force on the thread 2, causing the thread 2 to tighten the soft tissue. The operating segment 22 is used by a user to manipulate the thread 2 to tighten the soft tissue. The mounting base 1 includes a fixing structure 11 for securing the operating segment 22 after the user completes the manipulation.

[0034] Please note that, please refer to Figure 6In this application, the active section 21 of the thread 2 refers to the part that interacts with the elastic member 3 and moves with the elastic member 3 when the elastic member 3 is deformed. The operating section 22 refers to the part that is operated by the operator during the process of using the thread 2 to tighten the soft tissue. The operating section 22 and the active section 21 both have a certain length, and the thread 2 also includes a tightening section 23 for tightening the soft tissue. It should be noted that for soft tissues of different sizes, the position and length of the active section 21, the operating section 22, and the tightening section 23 are not fixed. The definition of the active section 21, the operating section 22, and the tightening section 23 in this application is described in the state of tightening the soft tissue at a certain time. For soft tissues of different sizes, the corresponding lengths of the active section 21, the operating section 22, and the tightening section 23 may also be different. For soft tissues at different times, the soft tissue sizes are different, and of course, the corresponding active section 21, the operating section 22, and the tightening section 23 may also be different. As for the tightening section 23, when the volume of the soft tissue changes significantly, part of it may become part of the operating section at different times.

[0035] The operating section 22 can remain fixed under the action of the fixed structure 11. Since the movable section 21 of the silk thread 2 is connected to the elastic part 3, after the silk thread 2 tightens the soft tissue and the soft tissue shrinks, the movable section 21 of the silk thread 2 can tighten the silk thread 2 under the elastic force of the elastic part 3, maintaining the tightening effect on the soft tissue, thereby reducing the frequency of tightening operations on the silk thread 2, and even there is no need to tighten the silk thread 2 during the soft tissue removal process.

[0036] The thread 2 may be any feasible form in the medical field in the prior art, for example, an elastic thread or a flexible thread without elasticity.

[0037] To further facilitate installation, in one embodiment, please refer to Figure 3 and Figure 6 The mounting base 1 includes a base 12, and the fixing structure 11 includes a pressure cover 110. The base 12 and the pressure cover 110 clamp the operating section 22 to fix the operating section 22. In some other embodiments, in addition to using the pressure cover 110, a tie-wire post for tightening the wire 2 can also be provided on the base 12. After the wire 2 is tightened, it is tied to the tie-wire post. In some other embodiments, fasteners, such as fastening screws, can also be used to tighten the operating section 22. In some other embodiments, the operating end can also be bonded and fixed to the base 12 by bonding.

[0038] Specifically, in one embodiment, please refer to Figure 6 and Figure 9Before the soft tissue elastic tightening device is tightened, the gland 110 and the base 12 are separated, and the thread 2 is connected to the elastic member 3. In some other embodiments, before the soft tissue elastic tightening device is tightened, the thread 2 can also be separated from the elastic member 3, requiring the user to assemble it on site.

[0039] In one embodiment, please refer to Figure 3 、 Figure 7 and Figure 8 In order to make the pressure cover 110 better compress the wire 2, the pressure cover 110 includes a cover body 111 and an extrusion column 112. The base 12 has a base hole 121. The extrusion column 112 is used to support the wire 2 and is inserted into the base hole 121. The operating section 22 is clamped and fixed between the extrusion column 112 and the base hole 121. The extrusion column 112 is more convenient for clamping the wire 2. In some other embodiments, the extrusion column 112 can also be provided on the base 12, and a pressure cover hole for inserting the extrusion column 112 can be provided on the pressure cover 110. In some other embodiments, in addition to the way in which the extrusion column 112 and the hole are matched, any other feasible form can also be used to compress the wire 2, such as fixing a flat plate on the inner side of the pressure cover, compressing the wire through two flat plates, or directly compressing the wire through the cover body.

[0040] In one embodiment, please refer to Figure 3 , the pressure cover 110 and the base 12 are fixed together by interference fit. Specifically, in one embodiment, please refer to Figure 3 and Figure 9 The gland 110 is provided with a gland column 113, and the base 12 has a positioning hole 122 for inserting the gland column 113. The gland column 113 is interference-fitted with the positioning hole 122. In some other embodiments, the gland 110 and the base 12 can also adopt other interference-fitting methods, such as the gland 110 having a gland groove and the base 12 having a protrusion, and the protrusion is interference-fitted with the gland groove.

[0041] In one embodiment, please refer to Figure 7 and Figure 8 , the number of the gland columns 113 is more than two, and the gland columns 113 correspond to the positioning holes 122 one by one. In one embodiment, please refer to Figure 7 and Figure 8 , the number of the gland columns 113 is six. In some other embodiments, the number of the gland columns 113 can be set to one, two, three, four, five or more than seven as needed.

[0042] In some other embodiments, the pressure cover 110 and the base 12 can be fixed together by snap-fit ​​connection, or fixed together by fasteners such as screws, or fixed together by welding or bonding, or fixed together by magnetic attraction.

[0043] In order to reduce the shaking of the wire 2, in one embodiment, please refer to Figures 4 to 6 The base 12 has a wiring groove 123, in which at least a portion of the operating section 22 is located. The base hole 121 has a socket 1211 for inserting the extrusion column 112, which is located on the wall of the wiring groove 123. At least a portion of the wire 2 is located within the wiring groove 123, making it easier for the extrusion column 112 to squeeze the wire 2. In some other embodiments, the socket 1211 of the base hole 121 can also be located on the flat surface of the tablet.

[0044] Since the elastic member 3 needs to be deformed and movable, in order to avoid the adverse effect of the operating end on the elastic member 3, in one embodiment, please refer to Figure 3 、 Figure 7 and Figure 8 One end of the extrusion column 112 is connected to the cover 111, and the other end is a pressing end 1121 that presses against the wire 2. The pressing end 1121 has a guiding slope 1122. The guiding slope 1122 is used to guide the extrusion column 112 into the base hole 121 and guide the wire 2 away from the elastic member 3. This makes the operating section 22 of the wire 2 less likely to interfere with the elastic member 3, which helps improve the reliability of the entire device during use.

[0045] In some other embodiments, under the premise that the guide wire 2 does not need to move in a direction away from the elastic member 3 , the pressing end 1121 of the extrusion column 112 may also be a plane.

[0046] In one embodiment, please refer to Figures 4 to 6 The wiring groove 123 includes a groove bottom wall 1231 and a first groove side wall 1232 facing the location of the elastic member 3 , and the guide slope 1122 is used to guide the wire 2 to move toward the first groove side wall 1232 .

[0047] Specifically, in one embodiment, please refer to Figures 4 to 6 The base 12 has an elastic member groove 124, which is used to guide the deformation of the elastic member 3. Specifically, the elastic member groove 124 contacts the elastic member 3, so that the elastic member 3 is deformed under the guidance of the elastic member groove 124. Specifically, in one embodiment, please refer to Figures 4 to 6 The elastic member 3 is a coil spring 30. One end of the coil spring 30 can reciprocate within the elastic member slot 124, and the other end can be fixed to or abut the base 12. The length direction of the coil spring 30 is the extension direction of the elastic member slot 124. In some other embodiments, in addition to using the elastic member slot 124 to guide the deformation of the elastic member 3, a guide rod can also be used. For example, a guide rod can be used to pass through the coil spring 30 so that one end of the coil spring 30 can only reciprocate in the length direction of the guide rod.

[0048] In one embodiment, please refer to Figures 4 to 6 The elastic member slot 124 and the wiring slot 123 are arranged side by side, with the first slot sidewall 1232 facing the elastic member slot 124. This arrangement is more compact and reduces the size of the device. In some other embodiments, the extension direction of the wiring slot and the extension direction of the elastic key slot can also form an angle greater than 0 degrees. The wiring slot and the elastic key slot are close to each other at the location where the wire is introduced into the base. This makes it easier to introduce the operating section and the movable section into the base from the same location.

[0049] In one embodiment, please refer to Figures 4 to 6 The base 12 has a wire positioning groove 125, and the wiring groove 123 extends along the first direction. The wire positioning groove 125 and the wiring groove 123 are arranged in the first direction. The wire positioning groove 125 is used to make the operating section 22 at the bottom of the elastic member groove 124. For details, please refer to Figure 5 In one embodiment, the cross section of the wire positioning groove 125 is inverted conical, and the wire 2 is less likely to move in the wire positioning groove 125. In one embodiment, please refer to Figures 3 to 6 When the guide slope 1122 on the extrusion column 112 guides the wire 2 to move away from the elastic member 3, the wire positioning groove 125 can prevent the wire 2 from moving as a whole, which is conducive to the extrusion column 112 to extrude the wire 2.

[0050] Specifically, in one embodiment, please refer to Figure 5 The bottom wall surface 1231 of the wiring groove 123 is a concave arc surface. The two side walls of the wire positioning groove 125 are arranged in an inverted eight-shaped shape, which is conducive to positioning the wire 2.

[0051] Since the guide slope 1122 needs to guide at least part of the wire 2 to move away from the elastic member 3, in order to prevent the wire 2 from separating from the extrusion column 112 after deformation, in one embodiment, please refer to Figure 5 and Figure 9, the first groove sidewall surface 1232 includes a convex convex section 12321 and a concave section 12322, the concave section 12322 is connected to the groove bottom wall surface 1231, and the concave section 12322 and the convex section 12321 have a smooth transition. The convex section 12321 can block the silk thread 2. Under the action of the first groove sidewall surface 1232 and the guide slope 1122, the silk thread 2 can be squeezed by the extrusion column 112 and is not easy to separate from the extrusion column 112. In addition, the convex section 12321 can reduce the sharp corners on the base 12, so that the top of the first groove sidewall surface 1232 is not easy to form a sharp structure. Of course, in addition to the above method, there are many ways to avoid the silk thread 2 from being separated from the extrusion column 112 after deformation, such as setting another inclined surface at the extrusion column 12, which forms a groove with the guide slope 1122 to block the operating section. For another example, a stopping protrusion is provided on the extrusion column to prevent the wire 2 from separating from the extrusion column 112 .

[0052] In some other embodiments, when the angle of the first groove sidewall surface 1232 is appropriate, the first groove sidewall surface 1232 may also be an overall concave arc surface.

[0053] In one embodiment, please refer to Figure 7 The gland column 113 includes a first gland column 1131 and a second gland column 1132, and the first gland column 1131 and the second gland column 1132 are spaced apart. The gland 110 includes a gland wire groove 114 between the first gland column 1131 and the second gland column 1132. After the gland 110 and the base 12 are installed together, the gland wire groove 114 and the wire positioning groove 125 are opposite to form a wire hole, and the wire hole allows the operating section 22 and the movable section 21 to pass through.

[0054] In one embodiment, please refer to Figure 7 and Figure 8 The number of extrusion columns 112 is two or more, and each extrusion column 112 is spaced apart along the extension direction of the wire 2. This makes the operating section 22 less likely to loosen and better secures the operating section 22. Specifically, the number of extrusion columns 112 can be any feasible number, such as two, three, or four. In some other embodiments, the number of extrusion columns 112 can also be one.

[0055] Regarding the elastic member 3, in one embodiment, please refer to Figure 6 The coil spring 30 is in a compressed state when the thread 2 is tightening the soft tissue. The movable section 21 is connected to one end of the coil spring 30, and the thread 2 is led out from the other end of the coil spring 30. In this way, the movable section 21 of the thread 2 moves within the coil spring 30 and is not easily entangled with the coil spring 30 and stuck.

[0056] In some other embodiments, the coil spring 30 may also be in an extended state when the wire 2 tightens the soft tissue. Compared with the coil spring 30 in a compressed state, the coil spring 30 in the extended state occupies a larger space.

[0057] In one embodiment, in order to facilitate the installation of the coil spring 30 and the movable section 21, the movable section 21 can also be connected to a baffle to apply pressure to the coil spring 30. The baffle can be fixed to one end of the coil spring 30 or can only be used to stop the coil spring 30.

[0058] It should be noted that in the present application, the movable section 21 is connected to the elastic member 3, which means that force can be transmitted between the elastic member 3 and the movable section 21, including both being directly connected, being connected through other intermediate parts, and not being connected but only achieving power transmission through a specific matching method.

[0059] In one embodiment, please refer to Figure 6 Since the movable section 21 passes through the coil spring 30, in order to facilitate the extraction of the movable section 21, a threading hole communicating with the threading hole is provided on the base 12.

[0060] In one embodiment, please refer to Figures 1 to 9 , the soft tissue elastic tightening device is used as follows:

[0061] Wrap the wire 2 around the soft tissue that needs to be tightened, and tighten the operating section 22 of the wire 2 after passing through the wiring groove 123 and the wire positioning groove 125. The coil spring 30 is compressed, the soft tissue is tightened, and the operating section 22 is fixed to the base 12 through the pressure cover 110.

[0062] The above specific examples are used to illustrate the present application, which is only used to help understand the present application and is not intended to limit the present application. For those skilled in the art of the present application, based on the concept of the present application, they can also make some simple deductions, modifications or substitutions.
